Threaded Drill Bits cover regular, retrac and reaming types. With stronger button-fixing ability, longer service life, better wear-resistance and impact-resistance performance, they are widely used in tunneling, underground mining, open pit mining,anchoring and other large-scale construction projects.
Thread button bits made with high quality of best quality alloy steel bar and tungsten carbides, through heat treatment so that it can withstand the toughest rock drilling demands, and transmit intensive impact energy into the rock with the least possible loss of energy
